The best thing McCaskey said was they would not be tied down to a specific type of coach. The purposefully went offensive minded coach with Trestman, stable old guy in Fox (to help Pace adjust) and then offensive guy with Nagy. If the next guy hires an OC/QB coach that gets it right and moves on to another job, it will be because Justin Fields is a stud, and then I won't care who the next coach is.
